R&R-Evaporator

To Replace the Evaporator:

(Assuming all steps for removal of the thrust bearing, breaker, auger and water seal have been performed).

1.Recover the refrigerant from the ice machine.

2.Unsweat the refrigerant connections:

a.At the thermostatic expansion valve outlet.

b.At the suction line at the joint about three (3) inches from the evaporator.

3.Remove the evaporator.

4.Unsweat the drier from the liquid line.

5.After installing a new water seal in the new evaporator (see “to Replace the Water Seal) sweat in the new evaporator at the old tubing connections.

6.Install a new drier in the liquid line.

7.Evacuate the system until dehydrated, then weigh in the nameplate charge. Check for leaks.

8.Install auger, breaker, breaker bearing assembly and ice discharge chute in reverse order of disassembly.

To Reassemble the Evaporator and Auger:

1.After the gear motor has been inspected, fasten the evaporator to the gear motor. Torque the bolts to 110 inch pounds

2.Lower the auger into the evaporator barrel, slightly turning it to match up with the drive end. Do Not Drop the auger into the evaporator.

3.Complete the reassembly by reversing the disassembly for the breaker and thrust bearing.
